I've been putting a lot of thought into where to go with this...
Considerations
1) I am not an actor, nor do I aspire to be
2) I have tried directing, and I was not very good at that either (the only thing worse than bombing on stage, is watching people who are doing you a favor bomb on stage because you are a bad director)

Alternative approaches I have been thinking about, and possible complications:
1) Pure Animation
-I really like the way the character is in the real human world. If I make a pure animation, the aesthetic analogy of the displacement of naive ambition in the viewers' world is lost.
2) I could play all the characters myself, just editing and shooting until I get something acceptable.
-This might wind up looking like some sort of Eddie Murphy movie (The Klumps), only I am pretty self conscious, so it would probably be pretty awkward to watch.
-There are performers who have made a career out of bombing on stage (Andy Kaufman), but I am not sure making a spectacle out of one's self to amuse the audience is good for the audience or the performer. It draws out mockery and a snide kind of ignorance, that might be useful in my concept, but I really didn't want to turn myself into Andy Kaufman.
3) Illustrated book, or a game.
-I don't know enough about writing or video game creation to begin to do these yet.
4) Rely on off screen action
-I need to learn more cinematic narrative devices to make this work. Maybe interviews, or some sort of quasi-documentary... I might be able to make a puppet, film people actually interacting, and splice the CGI in to make a believable performance, like Chris Angel (the street magician who films real people's reaction to a simple trick on the street and splices in video special effects to make the TV audience believe the effects are live).
